Dynamic Control of the Efficiency of Waterflooding of Low-Permeability Reservoirs by Horizontal Injection Wells With Transverse Multi-Stage Hydraulic Fractures

Abstract

At the pilot area of the oilfield in the Khanty-Mansi Autonomous Okrug, pilot works are being carried out to increase the development efficiency of low-permeability reservoirs using horizontal production and injection wells with transverse multistage hydraulic fractures (A.Shurunov et al., 2018). The paper describes the results of one stage of pilot works – the shifting of the central horizontal well into the injection and equipping this well with a fiber-optic system (FOS) for monitoring the downhole temperature field (DTS) and vibroacoustic oscillations (DAS). This work is a continuation of the work (A.Shurunov et al., 2018) and (R.Galeev et al., 2018) in the field of development of delivery methods for FOS in multiple-fractured horizontal wells (MFHW), testing the technology of DTS and DAS to evaluate the effectiveness of waterflooding of low-permeability reservoirs and monitoring the propagation of waterflood-induced fractures in injection horizontal well with transverse multistage hydraulic fractures.
